From the original RFC it seems like .org was always intended
to be a "miscellaneous/none-of-the-above" domain. The idea that it might be reclassified
as only appropriate to US tax code 501(3)c type organizations is too grotesque to
be true, even though some folks here seem to be implying that that's what ICANN means.
First of all the web is international, not a province of the US Internal Revenue
Service. Second, while it may make sense to limit .org to individuals and groups
for uses that do not involve profit-making, that should not be confused with the
local/national "non-profit" tax status of the group or individual.

As for how to
limit .org to uses that don't involve profit-making, other than using the honor system
the only way I can think of is to say that if you own a .com domain you can't also
own a .org domain, but I'm sure there will be people who wear both hats who will
disagree with that idea!
